1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Stable radicals are spin-active species with a plethora of proposed applications in fields from energy storage and molecular electronics to quantum communications. However, their optical properties and vibrational modes are so far not well understood. Furthermore, it is not yet clear how these are affected by the radical oxidation state, which is key to understanding their electronic transport. Here, we identify the properties of 1,2,4-benzotriazin-4-yl, a stable doubly thiolated variant of the Blatter radical, using surface-enhanced Raman scattering (SERS). Embedding molecular monolayers in plasmonic nanocavities gives access to their vibrational modes, photoluminescence, and optical response during redox processes. We reveal the influence of the adjacent metallic surfaces and identify fluctuating SERS signals that suggest a coupling between the unpaired radical electron and a spatially overlapping vibrational mode. This can potentially be exploited for information-storage devices and chemically designed molecular qubits.
